博客主要围绕EJB、HTML和应用部署展开。EJB查找引用有不同写法；HTML文档类型声明有简化写法；在应用部署到集群农场时出现‘Failed to setup clustering’问题，原因是Tomcat的jboss - service.xml中缺少对服务的依赖，给出了相应的修复代码。

EJB

Object ref = context.lookup("java:/comp/env/ejb/Fibo");

instead of Object ref = context.lookup("Fibo");

HTML

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

instead of <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

DEPLOY

Go to Succeed in deploying applications to the cluster farm and read the solution there.

"Failed to setup clustering", what does it mean?

[JBossCacheService][main] jboss.cache:service=TomcatClusteringCache service to Tomcat clustering not found
[JBossCacheManager][main] JBossCacheService to Tomcat clustering not found
[TomcatDeployer][main] Failed to setup clustering, clustering disabled

Since 3.2.6, HTTP session replication is based on JBossCache, and more precisely the TomcatClusteringCache? service.
In 3.2.6, 3.2.7, 4.0.1 and 4.0.1SP1, the dependency on this service is missing in Tomcat's jboss-service.xml.

To fix it, please edit /all/jbossweb-tomcat5x.sar/META-INF/jboss-service.xml and enable the <depends optional-attribute-name="CacheName?"> element, update the MBean ObjectName as well as the <depends> element itself.

The resulting code should look as follows:

<depends>jboss.cache:service=TomcatClusteringCache</depends>

instead of

一切OK。GO，GO，GO
